had my aircon fixed(again) last week; while stuck in EDSA kahapon, napansin ko na even without stepping on the gas and naka primera, umaandar pa rin ung kotse pag engage na ung VSV ng aircon. does this mean na masyadong mataas ung idle?

i also suspected na baka sliding clutch, but i did the 4th-gear test -- i.e. put the car to a full stop, then tried to launch it while at 4th gear -- ok naman.
